2'7 Claims.

The present invention relates to ornamenting machines, and work supports thereof, which are used in the manufacture of shoes to provide fitted shoe uppers with ornamental cut-outs or perforations. By a fitted shoe upper we mean one that is finished, at least to the extent of being lined, but which may or may not be closed at the heel.

In ornamenting fitted shoe uppers, it is often desirable to provide the opposite side faces thereof with cut-outs or groups of perforations, the cut-out or group of cut-outs or perforations on one side face being the opposite duplicate laterally, but not longitudinally, of the cut-out or group of cut-outs or perforations upon the other side face. Heretofore, these opposite duplicates have been formed by the same die, acting in one cycle of operations of the ornamenting machine to form the ornamentations on one side face .of the fitted shoe upper and acting in another cycle of operations of the machine to form the ornamentations on the other side of the fitted shoe upper.

In order to form the opposite duplicate ornamentations by the same die, it was necessary to out into one side face of the fitted shoe upper from the grain or finished face thereof in one operation, and to out into the other side face of the fitted shoe upper from the lined face thereof. To accomplish this, it was necessary for the operative of the ornamenting machine to place the fitted shoe upper upon the work support, locate the fitted shoe upper on the work support by means of. a combined clamp and gage registerable with some part of the grain or finished face of the fitted shoe upper, push the work support carrying the clamped upper into the position of pressure, trip the clutch to cause the die to ornament one side face of the fitted shoe upper, withdraw the work support from the position of pressure into the position of clearance, unclamp the fitted shoe upper, remove the fitted shoe upper, turn it inside out, place the fitted shoe upper, turned inside out, upon the work support, regage and reclarnp the turned inside out fitted shoe upper, the gage and clamp acting upon the lined side of the remaining uncut side face of the fitted shoe upper, return the work support carrying the gaged and clamped upper to the position of pressure, retrip the clutch to cause the die to cut the other side face of the fitted shoe upper from the lined face thereof, and return the work support to the position of clearance. Experience has demonstrated that it is practically impossible to relocate the turned inside out fitted shoe upper on the work support for the second ornamenting operation exactly as the fitted shoe upper was located on the work support for the first ornamenting operation. In consequence, the ornamentations were inaccu- 5 rately placed on the side face of the fitted shoe upper during the second ornamenting operation, resulting in a lack of correlation between the ornamentations on the opposite side faces of the finished shoe. 10

Moreover, there is a distinct difference in appearance between the ornamentations in the grain or finished side faces of the finished shoe, those ornamentations made by cutting through from the grain or finished face having attractive burnished edges, while those made by cutting through from the lined face have unattractive burred edges.

In some ornamenting machines the dies are located above the work, while in other ornamenting machines the dies are located below the work, but it is clear that in both types of machines as operated heretofore, the formation of opposite duplicates laterally, but not longitudinally, in the opposite side faces of the fitted shoe upper necessitated the inversion of the fitted shoe upper at some stage of the operation either subsequently to the first ornamenting operation and prior to the second ornamenting operation, or vice versa.

Ihe principal object of the present invention is to produce an ornamenting machine by which the opposite side faces of the fitted shoe upper may be ornamented in a single machine cycle, preferably simultaneously.

To the accomplishment of this object, a feature of the present invention contemplates the provision in an ornamenting machine having ornamenting means and means for supporting a folded fitted shoe upper, of means for moving the ornamenting means and the work supporting means relatively to cause the ornamenting means to ornament the opposite side faces of the folded fitted shoe upper in a single machine cycle, preferably simultaneously.

In the broader aspects of the present invention, it is immaterial into which face of the folded fitted shoe upper the ornamenting means first penetrate, so long as the opposite side faces of the folded fitted shoe upper are penetrated in a single machine cycle or simultaneously. In order, however, to prevent contrast in appearance between the edges of the ornamenting means on the opposite side faces of the finished shoe it is preferred to cause the ornamenting means to penetrate the opposite side faces of the folded fitted shoe upper from the same face thereof. Preferably, the face of the shoe upper into which the ornamenting means first penetrates is the grain or finished face, in order that the edges of the ornamentations formed in the opposite side faces of the finished shoe may both have the same attractive burnished appearance.

Heretofore, in many shoe upper ornamenting operations, it was desirable to support the fitted shoe upper on an elevated work support, called an anvil, constructed to permit the portion of the shoe upper to be ornamented to be supported flatwise, the side faces of the anvil being constructed to permit the other portions of the fitted shoe upper to be tucked out of the way, so as not to be caught between the ornamenting means and the pressing member. Usually, the anvil carried the dies, so that the portion of the upper to be ornamented was supported fiatwise upon the stripper plate thus necessitating the use of a clamp provided with a window, the internal edges of which acted as a gage in locating the upper properly relatively to the ornamenting means. Experience has demonstrated that it is undesirable to employ a work support which requires the use of a clamp or gage which masks or conceals the portion of the upper immediately surrounding the area to be ornamented. Moreover, with an anvil, it is difiicult and often impracticable to support fiatwise the portion to be ornamented, either of a Gypsy vamp having a California welt running along its median line or a fitted shoe upper having considerable swing.

A further object of the present invention is to produce a work support for supporting fitted shoe uppers for the ornamenting operation which will support fiatwise the portion of the upper to be ornamented, and which will permit its clamping and gaging without masking or concealing the portion of the upper immediately surrounding the area to be ornamented.

To the accomplishment of these objects, and such others as may appear hereinafter, the various features of the present invention consist in certain devices, combinations and arrangements of parts hereinafter described and then pointed out broadly and in detail in the appended claims which possess advantages readily apparent to those skilled in the art.

The various features of the present invention will be understood readily from an inspection of the accompanying drawings illustrating the best form of the invention at present known to the inventors, in which,

For convenience in disclosure, the various features of the present invention are illustrated and described as being embodied in the Western cut-out machine of the type disclosed in the patents to Altvater, Nos. 1,834,919 and 1,938,678 granted, respectively, December 8, 1931 and December 12, 1933.

In the embodiment of the invention, illustrated in the drawings, the frame of the machine is shown as including a base 8, (Fig. 4), which is rigidly secured to a permanent horizontal support 3 mounted on legs, (not shown). Integrally formed with the base is an irregularly formed boss l8 constituting a work supporting bed. An overhanging arm is integrally cast with the base 8 and includes the standard H and the overhanging head 52. In the upper parts of the standard and head is an elongated journal for the drive shaft 33. This drive shaft is operated intermittently from a suitable source of power acting through a clutch, (not shown), the construction and mode of operation of which is described in the Altvater Patent No. 1,834,919, at page 2, lines 32 et seq.

The shaft l3 carries at its front end an eccentric l which rotates within a strap l5 having a downwardly extending arm l8. The arm it extends between a pair of spaced arms N, forming upward extensions of a sliding plunger I8. A pin I 9 provides a pivot connection between the arm l6 and the arms H. The plunger i8 is mounted in a guideway formed on the front face of the head l2. A plate 2!] having a rectangular cut-out portion is attached to the walls of the guideway by bolts 2!. A die carrier in the form of a sliding block 22 is mounted in the lower part of the guideway in axial alinement with the plunger H8. The connection between the plunger and the die carrier is generally the same in construction and mode of operation as the connection shown in the Altvater Patent No. 1,938,678, so it is unnecessary to repeat that description.

The bottom face of the die carrier 22 is fiat to receive flatwise one face of a plate 2-3 having depending posts 24 upon the lower ends of which the upper or right die 25 is carried. The connection between the die carrier 22 and the plate 23 is substantially the same as between the corresponding parts disclosed in the Altvater Patent No. 1,938,678. The upper or right die 25, as shown in Fig. 8, is provided with perforating tubes 28, arranged in an ornamental design 27.

The lower or left die 28, as shown in Fig. 7, is provided with perforating tubes 29, arranged in an ornamental design 39, which design is the opposite duplicate laterally, but not longitudinally, of the ornamental design 27. The die 28 is mounted flatwise, with the cutting edges of the perforating tubes 29 directly upwardly, upon the fiat upper surface 3! of the work supporting bed 58. The die 28 is guided for movement from a position of clearance to and from a position of pressure between spaced rails 32 and 33, (Fig. 6) which are connected at their front and rear ends by cross-pieces 34! and 35, respectively. The crosspiece is provided with a forwardly directed tongue 39, provided with two vertical holes 37 which are received by pins 38 projecting vertically from the surface 3|.

The lower die 28 is provided with a rear extension 39 having a fork 40 formed therein which,

when the die 28 is located in the position of pressure, embraces the tongue 36. The tongue 36 thus acts as a stop in limiting the rearward movement of the die 28. The tongue 36 acts also as a gage to locate the homologous cutting edges of the perforating tubes 26 and 29 in the same vertical plane, respectively. The cross-rail 34 acts as a stop to limit the forward movement of the die 23 into the position of clearance.

The extension 39 on the die 28 is provided with laterally perforated legs-4l and 42 which support a cross-pin 43, the opposite free ends of which rest upon the upper surfaces of the rails 32 and 33, respectively. The pin 43 supports pivotally the depending arms of a yoke 44 to the flat upper surface of which the rear end of a plate 45 is secured. This plate 45 constitutes the work support. As it is positioned between the downwardly directed tubes 25 of the upper die and the upwardly directed tubes 29 of the lower die, the opposite sides of the plate 45 act as striking surfaces coopcrating with the tubes of the dies, respectively.

The work supporting plate 45 is provided with a blind slot 46, shapedto receive the forward portion of a folded fitted upper The fitted upper 47 is folded about the median line of its front portion. The fitted upper thus folded is inserted in the blind slot 46 when the die 28 is located in the position of clearance, (Fig. 2), and at a time when the plate 45 is swung rearwardly about the pin 43 as an axis. The folded fitted upper 41 is hung on the rear edge 48, which is shaped concavely to fit the inside median line of the folded fitted upper.

As shown in Fig. 5, the other edge 49 of the blind slot is bent downwardly and to the right, viewing Fig. 3, to bring it below the plane of the edge 48.

A combined clamp and gage 50 is pivoted by one end to the left side, viewing Fig. 3, of the front end of the plate 45, the gage swinging into and out of position in the same horizontal plane as the edge 43. At its free end, the gage 50 is provided with an operating button 5 I.

The extension 39 on the die 28 is provided with laterally perforated legs 4! and 42 which support a cross-pin 43, the opposite free ends of which rest upon the upper surfaces of the rails 32 and 33, respectively. The pin 43 supports pivotally the depending arms of a yoke 44 to the fiat upper surface of which the rear end of a plate 45 is secured. This plate 45 constitutes the Work support. As it is positioned between the downwardly directed tubes 26 of the upper die and the upwardly directed tubes 29 of the lower die, the opposite sides of the plate 45 act as striking surfaces cooperating with the tubes of the dies, respectively.

The work supporting plate 45 is provided with a blind slot 45, shaped to receive the forward portion of a folded fitted upper 41. The fitted upper 4". is folded about the median line of its front portion. The fitted upper thus folded is inserted in the blind slot 45 when the die 28 is located in the position of clearance, (Fig. 2), and at a time when the plate 45 is swung rearwardly about the pin 43 as an axis. The folded fitted upper 4'! is hung on the rear edge 43, which is shaped concavely to fit the inside. median line of the folded fitted upper.

As shown in Fig. 5, the other edge 49 of the blind slot is bent downwardly and to the right, viewing Fig. 3, to bring itbelow the plane of the edge 48.

A combined clamp and gage 50 is pivoted by one end to the left side, viewing Fig. 3, of the front end of the plate 45, the gage swinging into and out of position in the same horizontal plane as the edge 48. At its free end, the: gage 5!] is provided with an operating button 5|.

The rear end of the combined clamp and gage 50 is provided with an edge 52, the rear end of which is shaped convexly to engage the external median line of the folded fitted upper, and clamp it against the concaved edge 48. The rear end of the edge 52 is shaped also to register with some part of the folded fitted upper and thus act as a gage to locate the work on the plate properly for its ornamentation by the dies.

For purposes of disclosure the folded fitted upper is illustrated as a Gypsy vamp having a California welt along its median line and provided with cross-straps 53 connecting the portion of the opposite side faces to be ornamented. The rear end of the edge 52 is provided with a notch 54, which embraces one of the straps 53, and thus gages the work for the ornamenting operation.

For purposes of disclosure the various features of the present invention have been illustrated and described in an extremely simple form. The ornamentations may be perforations, cut-outs, chisel cuts, impression marks, inked marks or any desirable combination thereof. The dies may or may not be associated with stripper plates.

While the particulars of construction herein set forth are well suited to a simple structural form of the invention, it is not limited to these details of construction, nor to the conjoint use of all their features, nor is it to be understood that these particulars are essential, since they may be modified within the skill of the artisan without departing from the true scope of the actual invention, characterizing features of which are set forth in the following claims by the intentional use of generic terms and expressions, inclusive of various modifications.
